VEHICLE HUB AND XLE.

SPECIFICATION forming part of Letters Patent No. 405,932, dated June 25, 1889.

Application filed February 7, 1889. Serial N'o. 299,987. (No model.)

T0 all whom, it may concern:

Be it known that I, ISAAC MxnisoN WAR- NER, a citizen of the United States, residing at Bethel, in the county ot' Branch and State of Michigan,have invented a new and useful Improvement in Vehicle I-Iubs and Axles, of which the following is a speciiication.

My invention relates to an improvement in vehicle hubs and axles; and it consists in the peculiar construction and combinat-ion of devices t-hat will be more fully set forth liereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure lis an elevation, partly in section, of an axle-l spindle and wheel-hub embodying' my improvements. Fig. 2 is a sectional view of the same, taken on the line a; .r of Fig. l.

A represents the axle, which has the spindle B tapered toward its outer extremity and provided at its outer end and ata suitable distance from its inner end with spherical enlargements C.

D represents the axle-box, which is made in two longitudinally separable sections E. Each of the said sect-ions is providedwith a tapered longitudinal opening' E', adapted to receive the spindle, and is also provided with countersunk spherical recesses F to receive the balls or enlargements C ot the spindle when the said sections of the box are closed together thereon, as shown.

At the inner end of the axle-box is an annular recess G, into which extends a wooden tree II, that is clamped on the upper side of the metallic portion of the axle by means ot the clip-bolts I in the usual manner.

The hub K is provided with a longitudinal tapered opening I., in which the axle-box is adapted to be fitted. The outer end of the said opening is closed. The outer and inner ends of the hub are reduced in diameter, and are provided with metallic bands M N, which serve the usual purpose of preventing the wooden hub from split-ing, and also impart an ornamental iinish thereto. The inner band or ring N projects over the extending end of the tree II, and thereby forms a sand-band which prevents dirt and grit from entering the bearings. A transverse threaded opening O is made near the outer end ot the hub,

and a set-screw P is in the said opening, and has its'inner end extending through one and engaging the other of the sections of the box, thereby securing the said box-sections to the hub, and consequently locking the same on the spindle, so that the wheel can by no possibility be removed Jfrom the spindle without iirst unscrewing the said screw I).

R represents a tube, which extends through a transverse opening in the hub near its inner end, and has its inner end communicating with an opening S in one of the sections of the box. 'lhe outer projecting end of the said tube is threaded, and a cap 'l is screwed thereon. The tube R serves as a means for introducing oil or other lubricant to the axlespindle without the necessity of removing the wheel therefrom, it being only necessary to unscrew the cap T and pour the oil into the tube R when applying the lubricant to the wheel.

Having thus described my invention, I claiml. The combination of the axle having the spindle and the tree with its end projecting over the shoulder of the inner ends of the spindle, with the wheel having the box bearing on the spindle, and having the annular recess at its inner end, into which the proj ectin g end of the tree extends, and the sandband at the inner end of the hub extending over the projecting end of the tree, substantially as specified.

2. The tapered spindle having the spherical enlargements C, in combination with the box having the tapered bore adapted to engage the spindle and provided with countersunk recesses corresponding in form to the enlargements C, said box being 'formed of longit-udinally-separablc sections, the hub, and the transverse screw I), entering through and engaging aligned openings in the hub and in the separable sections of the axlebox,where by the latter is held rmly in the hub, sub stantially as described.

3. The combination of the spindle having enlargements formed thereon, the longitudinally-divided axle-box having recesses to accommodate said enlargements, the hub secured upon the axle-box by means of a screw passing through said hub and through outer IOO ends of the parts or sections of Vwhich said axle-box is composed, and a lubricating-tube extending transversely through one side of the hub and registering With a perforation in the'axleJoox, substantially as set forth.

1. The combination of the spindle having enlargements formed thereon, the longitudinally-divided axle-box having recesses to accommodate said enlargements, the non-perforate hub made solid at its outer end, and having a recess in its inner end to receive the axle-box, and a fastening-screw passing transversely through one side of the hub and through the sections composing the axle-box, which are thereby secured in the recess of the hub, substantially as set forth.

5. The combination of the spindle having enlargements formed thereon, the longitudinally-divided axle-box having recesses to acthrough one side of the huh and registering With aperforation in the axle-box, substantially as set forth.

In testimony that I claim `the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.

ISAAC MADISON `WARNER.
